REISLENT Application filed December 23, i921.

.7m/m if moy @officer/n.' le it Known that l, EDWARD l?. l'lnnnnnsoiv acitizen of the United States, residixw ftona., in the county ofTAV'olnsia an Y oi' Florida, have invented certain neuv seiulimprovements in Resilient Tires; do hereby declare the following to beclear. and exact description of the inventi on such as will enableothers skilled in the art to which it appertains to make end use thesame.

rlhe invention relates to tires designed more particularly forautomobiles and analogous motor vehicles and has for its object 'theprovision or a tire which possesses prac* ticallyY all the qualities ofa pneumatic tire but wliicn is proof against puncture, blowout and rinicut, and which does notl depend upon inflation to maintain the tire inoperative condition for neutralizing shock and vibration.

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

lllhile the drawings illustrate an embodiment of the invention it is tobe understood that in adapting. the same to meet dii ferent conditionsand requirements, various changes in the form, proportion and minordetails of construction may be resorted to Without departing from thenature of the inif'ention.

lReferring to the accompanying'drawings forming a part of theapplication,

Figure l is e sidJ view of a portion. or' a vehicle Wheel equipped witha tire en1bodying the invention, parts of the tire being brok n.51',

lli is a transverse section of the-tire supporting rim, showingthe parteon a larger scale, and.

'Wibnre 3 is fragmental perspective vienr of e of the inner clampmembers oit the ca im Corresponding and like parte are referred to inthe following description and designated in 'the several views of thedrawings by like reference characters.

The numeral l designates the rim of the Wheel snd the same may be fixedor demounta'ble depending upon the particular construction o1? the WhseThe rim l is of the channel type and is provided at opposite Sides W'outwardly extending flanges 2 casing` OF DAYTNA, FLORDA..

which are inwardly curved to insure interlocking engagement with thereinforced edges of the casing.

'lhe casing comprises a tread portion 3 and side mcn'xbers 4, the inneredge portions of which are outwardly curved to make interlockingengagement 'with the flanges 2 ol the rim l. The tread portion 3 of themay coiisist ol rubber or other suitable material and the side portions4l are preferably oit metal, the opposing` edge portionsl of the parts 3and 4 overlapping and being secured by suitable astenings (3, such asmachinescrews or bolts. The edge portions oi' the side members 4,secured to the tread portion 3, are let into the latter so as to Colneflush therewith on the outer side to present a smooth unobstructedsurface. The side nienibers et may each be a ring having a split. or themembers may consist oi a plurality or" sections.

An inner shoe T is placed against the inner side or' the 'tread portion3 and preferebly consists ot' metal and is retained in place by thesaine fastening means 6 employed to connect the parts 3 :1nd 4. The edgeportions ot' the shoe 7 project slightly beyond 'the edges oi the treadportion 3. A metal ring 8 is secured to the outer'side or eachprojecting edge portion of the shoe 7 and is adapted to engage acompanion ring 9 secured to the inner side ot the member fladjacent theinner edge of the part 3. Any tendency of the shoe 7 to turn relative tothe casing` 3 is obviated by the coaction of the rings S and 9 which arein alignment and in' substantially abutting relation.

rl'lie casingv is positively secured to the rim 1 by ineens oit' innerclamp members l() and outer clam 3 members ll, bolts or screws l2serving to connect the clamp members and passing through openings formedthe edge portions of the members The inner edge portions 5 of theeasing' are clamped between the members 10 and the rim flanges 2. rlheouter clamp members ll engage the outer side or the riin flanges 2 `andthe niembers and their edge portions taper and curve in oppositedirec-tions to obtain a neat and close lit against intermediate portionsbeing` heavy to sustain the strain of the draw or clamp bolts 12. Themembers 10 are lireferably "formed in sections to enable the device' tobe more the parts 2 and el, the

readily assembled and the members il may consist of one piece or thesame may consist of a plurality of sections.

A coil spring 13 constructed of spring wire of proper gage is disposedwithin. the casing and holds the saine expanded and tains the load andyields whereby to absorb shock and vibration. lhe inner sides -o't theclampmembers l0 are curved and formed with transverse grooves 14 whichconstitute seats to receive the coils or volutes of the spring 13whereby to prevent ciicumteiential movement of the spring and tomaintain the coils thereof in predetermined spaced?A relation. The coilsor volutes oi the spring be of' any material and it omitted the lsidemembers 4f may be attached directly to the edge: portions of the shoe 7.

`Wliat isclaimed is:

l. In a vehicle tire, a' casing, and inner and outer clamp membersconfiningr edge portions o't the casing and adapted to conine theflanges of a rim.

2. In a vehicle tire, a casing and inner and outer clamp membersconfining edge portions ot' the casing and the flanges ot' a rim, theouter clamp members having opposite edge portions tapered and reve 'selycurved to obtain a neat and close iit relative to the casing and iangesof the rim.

3. A resilient tire comprising a casing in cliiding a iexible treadportion and side portions of rigid material, projections eatemiing`inwardly from the side portions ot the casing, an inner shoe, and outerprojections at the edges of the inner shoe adapted to cooperate with theinner projections of the casing to prevent outward displacement ot saidinner shoe.

4. A resilient tire comprising a casing, in iici' and outer clampmembers in cooperative relation with edge portions ot the casing, theinner-clamp members having transverse grooves, and a wire coil withintliecasing and having its volutes seated in the grooves ot' the innerclamp members.

ln 'a tire of the character speciied, a casing comprising a iexibletread portion and rigid side members, rings secured to the inner sidesont said side members, a shoe within the casing, and rings attached totheouter side of the edge portions of the shoe.

and adapted to engage and cooperate with the rings attached to the sidemembers of the casi-ng whereby to prevent 'displacement ot screwsconnecting the clamp members, a

wire coil within the casing, the inner clamp members having transversegrooves to receive the convolutes of the Wire coil,.a shoe disposedbetween the wire coil and the tread `portion oi the casing, andoverlapping members between the edge portions of the shoe and sideportions of the casing to prevent displacement of the shoe.

8. in a tire ot the class described, a casing having a rigid edgeportion, inner and outer clamps one to eit er side of said rigid edgepoi-tion, the inner clamp being in engagement with the inner face of therigid edge portieri, the outer clamp being spaced from the rigid edgeportion, and clamp screws for clampingl the outer clamp member to theflange oitE a rim.

9. in a tire ot' the class described, a casing having a rigid edgeportion, inner and outer ciamps, one to either side ot' said rigid edgeportion, the inner clamp being in engagep,

nient with the inner face 'ot the rigid edge portion and the outer clampbeing spaced therefrom, clamp screws for clamping the y,

outer clamp member to the flange of ariin, a coil. within the easing,and the inner clamp having transverse grooves forming seats for thcconvolutes ot the coil. i

in testimony whereof l afx my signature in presence ot two witnesses.
